To beep down or not to beep down, that is the question!
The "EP" RFM says for;
"In-Flight Operations"; ENG - 97 to 100% RPM (N11).
"ROTOR RPM - POWER ON"; Continuous operation 97 to 100%
"FUEL FLOW VS. AIRSPEED" graphs; ENGINE RPM = 97%
Now that all said and done, I do prefer to only beep down when I am cruising at a sufficient cruise altitude to have time to beep back up if something happens.
